It has been a while since my last update, and thanks to the extension I could spend time working on other projects for my demo reel.
To answer some of the questions...
1) The points are renderman point primitive - motion blurred. I imported them into maya, and ribbed them out to disk as a multi points.
2) I will do some test with ribbing out a blobby pass and see how the foam looks
3) The foam is the same points I used for the mesh, because the mesh gets scaled in size it leaves areas open that shows particles and I simply used that as foam; this comes a a huge cost for my machine because of the unnecessary points that get passed to renderman that are hidden from the camera.
4) Because of the amount of particles, using any scripts was useless and would send me months behind completing this assignment.
Here is a new render movie more to come. I will spend this week doing a final render
